GEAR-TRANSMISSION MECHANISM- Specification of Letters Patent.

Application filed October 20. 1906. Serial No. 339,873.

(ii-Ill, a eil izen ol'the l'nited States, residing at l)el roll, in th county of Wayne and State of .\lichigan, have invented certain new and member 8, and 32 designates a washer which useful improvements in (lear-'lransmission .\leehani.-:m. ot'whieh the following is a. speeilieut ioll.

The object of my invention is to provide an lllllilUVttl gear-lrnnsmission mechanism par- |l('lll:2ll adapted for automobiles, motorboots. and the like, but susceptible of use in changing the speed or reversing the motion ol' :m driven sbal't.

For a lull understamling ol' the invention and the merits thereof and also to acquire a knowledge of the details of construction reference is to be. had to the following description and accompanying drawings. in which' liigure l is a horizontal sectional viewof my improved gear-tra-nsmission mechanism. Fig. .2 is a longitudinal sectional view of the same. the section being taken approximately on the line (I l) of Fig; 1. transverse section taken approxinmtely on the line A B oll ll igs. I end 2 and looking toward the left. Fig. 4 is a detail perspective view of the male clutch member detached. Fig. 5 is at similar view, partially broken away,

of the complemental clutch member; and Fig. 6 is a detail view ol the slnltmg-lork detached.

Corresponding and like parts are referred to in the following description and indicated. in'all the views of the drawings by the same reference characters.

The ease to inclose the operative parts of my improved gear-transmission mechanism may beol' any desired construction and design, and in the present instance said ease embodies a lower section 1, provided withenrs 2, by which it may be secured. by bolts 48 or the like to the top section 3. The section 3 may be )rovided at its top with a handhole 49, provided with a closure 4.

5 designates the drive-shaft, which is arranged to be coupled to the motor orprime mover (not shown) by any suitable means, and said shaft is journaled in a bushing 31 or by means of bell-bearings within the case and is also journaled at one end within. a preferably cylindrical bearing 50 it the sleeve 8, said sleeve being also ournalad in the o posite end of the casing by means of s busliing 31 or by ball-bearings. The sleeve 8 is re duced et its projecting end and constitutes a l Fig 3 is n I l l l l l l 1 9 shown in Fig. 1.

portion of the driven shaft, which is operativel y connected to the rearwheels of the automobil'e or to the parts to be'driven in any stumble manner.

30 designates a collar secured to the sleeve encircles the sleeve bearing within the case and bears against the inner side of the sd-' jacent bushin 31.

The drive-shatt 5 is provided with a 1011 ie; f

6 within the case, an ta tudinal 'slot' or space male clutch member 23 is prpvided with a v bore 53, by which it is inounted'on the said shaft and is provided with recesses 37, within which the pivoted ends of the keys 21 are located and are mounted u on'pins 36. The keys 21 extend longitudina y within the slots 6 of the drive-shaft 5, and their freeends are pressed outwardly by a, spring 22, which is riveted or otherwise secured to one of the keys 21 and bears against the other, as best The outer free ends of the keys 21 are rovided with oppositely-extending beveled ugs 41.

The drive-shaft 5 carries a plurality of gear-wheels which are loose thereon. In the present instance three of these gears are shown, (designated 10, 11, and 12,) and said 1 gears are provided with nterposed washers :33 to keep them properly spaced, and also with outside washers 32, one ol' which bears against the ad acent bushing 31 and the other of which bears against 1i collar 35,

keyed on the shaft 5, and inter used between the said washer and the male 0 utch member 2%. Each of the gear-wheels l0, 1], end 12 is provided with kcyways 40, located (1' metrically opposite to each other and esigned to receive the beveled lugs 41 on the outer ends of the keys 21 for the lpurpose ol' rigidly securing the sold gear-whee s upon the shaft. i

in order to shift-the mole clutch member 23 back and forth upon the shaft 5 to effect the coupling connection of any one of the wheels 10, ll, and 12 with the shaft, I provide the shifting-fork 28, the two arms 47 of i which are rovidcd at their extremities with lugs or rol ers 52, working within an annular groove 26 on said clutch member, The main extension of the shifting-fork is provided with a bore 54, which receives the shifting-rod 9, and the shifting-fork is pinned or otherwise iixcd to said rod. The rod 9 is mounted to have a-li 1igitudinulsliding movement in the case and issupportcd by means 27 of the female clutch member spacing-washers the gear-wheel 10.

of an apertured depending lug 44 intermediate of the ends of the case and a boss43. One end of the shiftingyrod 9 projectsoutside of the'case, as indicate hat 45, and,is arranged for connection in any suitable manner to the shifting-lever. {Not shown.) 1

The male clutch member 23 is provided with tongues 24, which are shown as diametrically opposite-and which are beveled at one side, as indicated at 25, so as to slip more readily in thediametrical ly opposite grooves 29, which in the present instance is formed 'on the inner end of the sleeve which is connected towhe driven shaft 8. The grooves 27 are also beveled at one side, as indicated at 25, to enable the tongues 24 to slip therein with ease. By thismeans the drive-shaft 5 may be coupled for direct driving connection with the driven shaft 8. v Mounted within. the case on the sleeve of the driven shaft 8 is a gear-wheel 13, fixed on said sleeve by a key 39 or the like. This gear-wl'ieel is conn'ectedto the'counter-shaft 7, extending from end to end of thecase alongside of the shaft 5 and journaled at its ends in bushings 31. or in any other desired-form of hearing. The connection is effected by means of a geanwheel 17 held on the shaft 7, as by a key 38 or the like, and interposed between two washers 312, a' ainst one of which bears athrust-collar 34, (eyed orpinned on the shaft: The counter-shaft 7 also carries gear-wheels 14;, 15, and 16, which are all fixed thereon, as by keys 38, and are provided with 33 and outer washersBZ, against one of which a thrust-collar 34 bears, shown. The gear-wheels l5 and 16 mesh with the geanwheels 1 1 and 12, respectively, while the gear-wheel 1.4 meshes with a reversing pinionor gear 18, which also meshes with The reversing-gear 18 is mounted on a shaft 19, journaled between two bosses 42 and 20 within the casing. The bottom portion of the casing may be provided with an extension 51, to which a drain-cock 4(3'may be attached for the purpose of drain ing oll oil. a i t In the m'actical operation of my improved gear-transmission mecl'ianism' it is manifest that the drive-shaft 5 may be coupled directly to the driven shaft 8 by shifting the rod 9, so as to carry the fork 2 to the right and-cause tho intercngagehie'nt ofthe two clutch members23 and 29, W In this direct coupling engagement of the parts the male clutch member 23 will be moved over'into' a position where the beveled lugs 41 of the keys :1 are located within the thrust-collar 35. To reverse the motion of the driven shaft 8, the shil'tinga'od .l is moved in the opposite direct ion, the keys 21 being carried sncressively through the l-;ey\vays of the gears 11 and 12 and slipping past the interposed collars 33 by means of the beveled formation of the lugs l l l ,beseen that finally spring up within the keyways of the gear 10, so as to couple this gear with the drive-shaft 5. As the gearwheel 10 meshes with the reversing-gear 18, which in turn meshes with the gear-wheel 14, it obvious that the counter-shaft 7 will be rotated in a-odirection to cause a reverse movement to be imparted to the driven shaft 8 through 1 he intermeshing connection of'said shaft and fneeounter-shaft by means of the two gear-wheels 13 and 17. To vary the speed of the driven shaft 8, the shifting-rod 9 is moved, soas to carr Y the beveled ends of the keys 21, into the keyways of either of'the gear-wheels 11 or 12, and as these gears vary relatively to the gearwheels 15 and 16 a consequent variation in speed will be effected;

Fromthe foregoing description, in connection with the accompanying drawings, it will I have provided an improved gear-transmission mechanism which will-be effective at all times through the operation of a single shifting-lever to either reverse the motion of a driven shaft or vary the speed of the same and. that the construction is a vcry simple one and durable and not liab'le'toiget outof order. k In the operation the motion is always ti'ansn'iitted (except when the shafts Sand 8 are directly, coupled) through the countershaft 7 and back td-the driven shaft by means 41; and said lugs of the gear-wheels 17 and 13.
